To all whom it muy concern:

Be it known that l. ltivnoxn Hmm', :i eitizen of the United Sintes. anda resident of Brooklyn. in the eimnty of Kings and 5 State of New York.have invented certain new and naelnl Improvements in llemonntnlilell'hechllinw. ot' which the following in ii specitieiition. .n

My pieitent invention relate# to vehicle l wheels and morepartienlarl'i'-to mieli wheehi iii which :i tire holding' i'iiii isdeiiioiiiital'ily Secured to the wheel proper whereby the iiiii can beremoved from the wheel witliont lirst removing the tire from the riin.

l (lne of the ohjoets of my invention is to provide a consti-notionwhereby rino; which do not preent any carved or iin-lined sin" faceadapted to be engaged hy clamps piay be deinonntahly .Hw-tired to thewheel in a strong and sa fe manner.

(lthei' ohieets` of iiiy invention are light neen and eheapneo` ofeomtrnetion and to provide ii eoiist'raetioii whieh van ha. need williany type of tire holding i-ini whatever.

lleretofore it haheen indio-sible to eni- 'ploy a denionntahle riin inl-neh envi-s where the periphery of the riin was straight and did notpre--ent any carved sin-fave to he engaged h v the clamping means andwherein :t0 the clamping devices held thel i'iin mainly by ii trictionalor expanr'ihle force. lt has therefore heen proposed to iiialte theserime of Hpeeial forni to. moet tho deiiinnds for n deinonntnhle rimwhichspecial rims are e.\'-

. 36 pensive to consti-net in: new rolls are required tu foi-in them andthey therefore have heen impractical. y

Whilel my invention is designed primarily su th t itv can he eiii'riedont with n eylin- 40 drioiif iitii it will he nnderrttuid that otherforms of rims nii'ht'- equally well he en iployed and that w iei'ein theterni rim"` is used in thtl siihjoined description and claims. any forniofrini is ni'eant, whether presenti ing n cylindrical oi' other surface.

` IAlan heretofore real tronhle has` h eon experienced in iipp yingdeinoiintahle rima to atandai'd wheels. For an example. mipc it istraire to equip an antoniohile wheel with ii denionntahle riin which inwheretofore been provided with n lixed riin only. The fixed riin isremoved and itis than necessary to ent'ior inea down the felly to ovarying amount to allow for the liners, u clamps' c. u. with adcnioanteberim.

Al wheelwrighta well know this is a ditlionlt tar-k and-one that. isuncertain in good results. By practicing niy invention this. vattingldown of the old felly is dispensed with im when it is desired to have nde GQ mountable rim-of a given size, a standard wheel of the nextsmaller sized telly is employed and n supplementary gell is lcenred tothe rim which takes np t e space between the iivfglwheel felly and thede- 65 nionntnhlo rim. roi' iiietnnt'e, if it il desired to have n M x4in. wheel. which means a 34 x4 in. rini must be employed, l. wheel 3:!x4in. used and a telly secured to the inner periphery of the riin andmovable with it is need to take tip the space between the 32x-1. wheeland the 34 x4 rim.

y invention comists in the novel nrrangcinents of parts and details` ofconstriic tion hereinafter more airticalarly described I6 and thenspeeiied in t e claims.

In the aoeoinpan ing drawings Figure l y illustrates, in side e eration,a vehicle wheel having my invention applied thereto. Fig.

' i.- an enlarged transverse section on the 80 lim- A:e .1f Fi v. l.Fig. 3 is ii seetitm on the linil'fi o Fig. :t and shows the manner ofobtaining a positive drive in btll directionh lwtween the wheel and thedeinoiint.- ahle riin.

ln oni-wing ont in invent-ion n standard wheel with lixed fel v isemploved. but the telly of the wheel is preferably the next smaller sizein dinan-ter thiin the sin of rini deaircd. 'llie linb of the wheel,indi- I0 rated at l. is provided with spoken 2 and l l'elly 5l lixed tothe end of the spokes tin in nsnal iii the art. l

'lhel .rim herein shown il what iq known as arna for ay quick detachable tire and one which it has heretofore beenpractically impossible to employ al ii doinonntahle rim as it does notprelent In surface to he engaged by tho detlchlbo damping means. Isecnreto the inner pori hery of the rim ii wooden el t5 concentric. with lthewhole] telly 8 and which onereles mid wheel telly. This eupplemenioltary telly ti is provided with c slordig of metallic attachments orbends local at intervals around its circumference. The It n taehments (tare preferably eonntersiink into' t ie elly 5 no that. their outer enrecos w no he flash with the periphery of the telly 6.

Preerably the clamps are-.1n the form of-wedges 8 equal innuxnber andloca,- tion to the attaclimente 6 and enter between mid attachments andthe band 7, the wed having a llat seat upon the hner or ban 7 und aninclined bearin on the attachments.

Preferably the attachments 6 are rovlded with projecting lugs 11 oneither si e of the bears. The wedges 8 are so formed al to enage theattachment 6 between the lu l1 n so that the sides of the w will ve a onthe sides of the up whe y any alip is prevented between the lied 8 andthe supplementary or demoun (e fell ll, thus obtaining a positive driveindirections.
